“Google is the elephant in nearly every corner of the Internet, from search and advertising to web-based e-mail, online mapping, and home-brewed video. With its share price setting new highs this fall, its market cap ($188 billion) is now large enough to buy the New York Times, the Washington Post, Gannett, and Time Warner -- twice. Or Facebook many, many times over.

“The problem is, Facebook's not for sale. And that's got Google running scared. It's an open secret in Silicon Valley that the company has been shopping around a nondisclosure agreement outlining its plan to create its own massive social network -- and asking anyone with a pulse to sign it.

“Google has to do something fast, because some of its best talent is starting to head for the exits. In July, Gideon Yu, finance chief at Google's YouTube, left for Facebook. Now other Google guys, stuck in the Googleplex and smelling a Facebook IPO that could turn early employees into early retirees, are also jumping ship. The latest defector: Benjamin Ling, the top engineer at Google Checkout, its online payment service. A Stanford comp-sci Ph.D., Ling will be overseeing Facebook's entire software platform. Losing finance types is one thing. But smart engineers are the lifeblood of a great tech company, and Ling was worth a pint, insiders say.”
